when the charging pile is provided with the matrix direct-current switch module, the charging pile closes a corresponding direct-current switch in the matrix direct-current switch module so as to conduct the charging module and a charging output interface connected with an external vehicle; otherwise, the charging pile directly closes the direct-current switch corresponding to the charging module;
when the error between the actual output voltage of the charging module and the working voltage of the current charging output interface is greater than or equal to the preset error threshold, the charging pile closes all the started charging modules in the step 10, and then the step 3 is carried out;
step 12, the charging pile continuously detects the charging requirement of the connected external vehicle, and the step 3 is carried out according to the charging requirement of the external vehicle, so that the external vehicle is continuously charged;
step 13, the charging pile randomly selects charging modules needing to be reduced from all charging modules corresponding to the current charging output interface, sends a single-point shutdown instruction to the randomly selected charging modules according to the addresses corresponding to the randomly selected charging modules so as to shutdown the charging modules, and the step 14 is carried out;
step 14, after the randomly selected charging module is shut down, if the charging pile has a matrix direct current switch module, the charging pile disconnects a corresponding direct current switch in the matrix direct current switch module to disconnect the charging module and a charging output interface connected with an external vehicle, and the step 15 is carried out; otherwise, the charging pile directly disconnects the direct current switch corresponding to the charging module, and the step 15 is carried out;
and step 15, the charging pile clears the group addresses of all the charging modules which are shut down in the step 14 one by one, and the states of all the charging modules are marked as idle, so that the charging modules marked as idle are repeatedly allocated and used again, and the step 12 is carried out.
